PR Newswire (US)
Complying with new proposed iDP interface standard, new bridge
chipsets from ST realize cost and time-to-market savings for TV
manufacturers GENEVA, Jan. 6 /PRNewswire-FirstCall/ --
STMicroelectronics (NYSE:STM), one of the world's leading
semiconductor companies, today announced it has developed the
industry's first 'bridge' chipsets for the proposed iDP (Internal
DisplayPort) standard to LVDS (Low-Voltage Differential Signaling)
translation for use in next-generation LCD TVs. The new chipsets
are compliant with the iDP interface standard recently proposed by
ST, in collaboration with LG Display, to the Video Electronics
Standards Association (VESA) TV Panel Task Group. Designed for the
connection between the TV-controller SoC (System-on-Chip) and a
TV-panel Timing Controller within a TV chassis, iDP is an advanced
technology based on DisplayPort, a proven industry-standard
technology that is an open and royalty free VESA standard. The new
chipsets from ST will be demonstrated for the first time at ST's
private suite for customers at CES 2010, January 7-10, in Las
Vegas. Built using DisplayPort technology and featuring low-power
design and low EMI (Electro-Magnetic Interference), these new
iDP-to-LVDS bridge chipsets from ST will provide robust
interoperability and cost effectiveness, enabling customers to
quickly validate the new interface standard and enable the
deployment of next-generation products with time-to-market
advantages. ST's first iDP-based solution comprises an iDP
transmitter and iDP receiver, the STiDP888 and STiDP880,
respectively. Together, these form a complete interface translator
for high-bandwidth panel-interface applications, redefining and
simplifying the panel interface by reducing number of wires,
connectors and signal traces, thus driving down the cost of
implementation for TV makers. The chipset solution comprises a
single-link iDP interface capable of transporting uncompressed
pixel streams up to 12.96Gbps bandwidth between TV SoC and LCD
panel module over four pairs of low-cost twisted wires or FFC (Flat
Flexible Cable) cabling. ST's iDP transmitter and receiver devices
are fully scalable: each chipset can support FHD (Full
High-Definition) video (at 1080p/30-bit per pixel) at 120Hz refresh
rate; two sets can support FHD-240Hz refresh rate panels. Both the
transmitter and receiver devices integrate high-speed Quad-LVDS
interfaces for conversion between conventional Quad-LVDS and iDP to
address transitional market needs. These products offer maximum
flexibility to TV manufactures and enable seamless transition to
iDP. In addition, the spread-spectrum technique, employed in
conjunction with iDP's self clocking, data scrambling and
inter-lane de-skewing architecture, bring additional cost savings
by eliminating external EMI-reduction components. The STiDP888 and
STiDP880 components are packaged in 164-ball LFBGA package and are
available for sampling now. Further information about iDP
Technology Aimed at implementing the connection between the
TV-controller SoC and Timing Controller within the TV chassis, the
iDP standard offers highly robust interoperability and cost
effectiveness, realized by leveraging the proven DisplayPort
technology in its simplest form. With a link operating at 3.24/Gbps
per differential pair, only 17 signals (eight differential pairs
and one Hot Plug Detect (HPD) signal) are needed to transport Full
HD 240Hz at 10 bits per color over the iDP link, substantially
fewer than the 96 signals required for a conventional LVDS link.
With the dynamic lane-count adjust feature, iDP is capable of
supporting pixel rate change due to events such as video frame-rate
change and 3D-stereo display timing without visual glitch on a TV
screen. The openness of the iDP standard, further enhances cost
effectiveness because it solicits competition by many component
suppliers without royalty considerations. About STMicroelectronics
